HDMI currently stops working after a system suspend/resume cycle. The cause is that the mode setting states in hardware gets lost and isn't restored across the suspend/resume cycle. The patch adds a very basic suspend/resume support to imx-drm driver, and calls drm_helper_resume_force_mode() in .resume hook to restore the mode setting states, so that HDMI can continue working after a system suspend/resume cycle. Since the suspend/resume hook can be called with drm_device pointer being NULL from driver data, we need a check on the pointer in the hooks. And to avoid using a stale pointer from driver data, it also clears driver data in .unload hook.
